# Decision Transformer model trained on medium trajectories sampled from the Gym Walker2d environment
This is a trained [Decision Transformer](https://arxiv.org/abs/2106.01345) model trained on medium trajectories sampled from the Gym Walker2d environment.

The following normlization coeficients are required to use this model:

mean = [ 1.218966, 0.14163373, -0.03704914, -0.1381431,   0.51382244, -0.0471911, -0.47288352,  0.04225416,  2.3948874,  -0.03143199,  0.04466356, -0.02390724, -0.10134014,  0.09090938, -0.00419264, -0.12120572, -0.5497064] 

std = [0.12311358, 0.324188,   0.11456084, 0.26230657, 0.5640279,  0.22718786, 0.38373196, 0.7373677,  1.2387927,  0.7980206,  1.5664079,  1.8092705, 3.0256042,  4.062486,   1.4586568,  3.744569,   5.585129 ]
